IMPROVEMENT IN PLows.

Specification forming part of Letters Patent No. 169,799, dated November9, 1875'; application filed September 11, 1875.

To all whom 'it may concern Be it known that I, IRVIN FREEMAN, ol'Corpus Christi, in the county of Nueces and State of Texas, haveinvented a new and Ilnproved Plow; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accom panyin g drawing, forming a part of thisspecification, in which- Figure lis aside elevation, partly in section;and 2, a detail view of shovel in front and sectional elevation.

The invention will lrst be fully described in connection with drawing,and then pointed out in cla-im.

A represents a plow-beam, on the top surface of which is fastened therack-plate a, and B a skeleton plow-frame, fastened to the beam by anend-slotted piece, b, and having` the open grooves bl b1. C is a leverpivoted to the heel b2, and having the pawl c, that works in the rack a.D is a lift-rod attached to pawl o, and extending up within easy reachot' the plowman. E is a curved rod, threaded at one end to receive anut, e, behind the lever, and having a hook, e', that lits into theshank-recess f of a shovel-plow, F.

After placing the toe b3 and hook e in the 'recess f, while the hooks ffenter the recesses b1, the lever C is carried backward nntil the parts BF are firmly held together, and then locked by the pawl c, that catchesin a tooth of racha. The shovel F can be locked and held on the skeletonframe B in a similar manner.

This mode of fastening' a subsoiler or shovel to the skeleton frame isfound, in practice, to be very easy and convenient.

Having thus describedmy invention, what I claim as new is Thecombination, with hook-rod E, holding shovel or subsoil plow to skeletonframe, of the lever C, having paWl c, Working in the beam-rack a, as andfor the purpose specified.
